External I/O Modules (Optional)
The following multiple analog or digital I/O modules mount externally to the Nexus®
1250/1252 meter. The Nexus® 1250/1252 meter supplies 12VA to its ports. You may
need to use additional power supplies, such as EIG’s 12V PSIO, to extend I/O capabil-
ity. See Sections 5.6.2 to determine power needed; see Section 3.3 for mounting
diagrams; and see Chapter 9 for details on installation and use of the Nexus®
External I/O modules.
